Flow or Leveling
When the paint does not dry to a smooth film after application, it results in brush and roller marks on the surface. This condition is Flow or Levelling and this defect is often unpleasant.
Possible Causes |
Solutions |
Paint is too heavy |
• Reduce the viscosity of the paint and get the correct consistency. • Check for correct viscosity using Zahn #2 viscosity cup. |
Faster Evaporation of the Solvent | Use solvents that evaporate slower, if the air temperature is higher. |
Improper Air Atomization | Adjust the spray gun |
Application of paint on Thin Surfaces | Apply paint on surfaces with more passes. Let the application be wet immediately. |
Increase in Air Movement | Reduce the draft |
